In electrical installations it is often of great importance completelyto eliminate the self induction of the conductors that interconnect thevarious apparatus. In the circuit arrangements for wireless telegraphapparatus, for instance, these self induction phenomena'are veryannoying.

The solution thus far arrived at consisted 'of the twisting together ofthe conductors or simply of locating the conductors near each other.However, the conductors cannot be connected to the apparatus unlesstheir ends are separated, whereby loops will be formed that may possessconsiderable self induction.

The object of the present invention is to provide an arrangement wherebythe self induction of the conductors is completely eliminated. v y yAccording to the present invention, the connections are so provided thateach conductor is composed of two wires and the ends of these two wiresare united in a manner to constitute a closed loop.

Attention is directed to theaccompanying drawing in which:

Fig. 1 is a cross section viewof a preferred modification of myinvention. v

. Fig. 2 is a schematicdiagram of Fig. 1. Fig. 3 is a diagrammatic viewfor illustrating the operation of my invention.

Fig. 4 is a cross section view of another modification of my invention.

Referring to Figs. 1., 2 and. 3, the preferred embodiment of myinvention com rises two conductors 1 and 2 arranged paral el to eachother in a common plane'and two other conductors 3 and 4 arrangedparallel to each other in another plane, the two planes being eachother. The conductors may be encased in the usual insulating materialv5.

Conductors 1 and 2 are joined together Referring to Fig. 3, ccniductors1 and 2' constitute one side at a circmt and. comin at right angles toeach other and bisectingtors 3 and 4 constitute'the other side. A s--sume currents flowing down thru conductors 1 and 2 and up in conductors3and 4. The ampere turns exerted by conductorsl and 2 tend to neutralizeas do the ampere turns exerted by conductors 3 and 4:. This results inthe substantial elimination of all self in-' duction between the variousconductors.

The invention is applicable irrespective of the number of conductorsemployed and 'it is ndependent of the character of the current emplo ed.The invention may be generally app ied to installations wherein theelimination of the self induction in the conduetors is desired.

In wireless telegraph stations in which In certain stations andparticularly in' stations installed on airplanes in which the alternatorwith the rotating discharger mount ed on the end of the shaft is locatedon the wings of the airplane at a fairly great dis-' tance from theoscillating circuit, conductors without self induction and arranged inthe manner described above should be used.

Referring to Fig. 4., I 'may construct .a' cable comprising a conductivecore. 10 forming oneside of a circuit and a plurality of conductors 11.arranged concentrically around the core 10 insulated from each other andfrom the core byinsulating material 12. While I have shown and describedvarious preferred embodiments of my invention I 90.-

do not limit myself to the same but may employ such other modificationsas come within the spirit and scope ofmy invention.

Having described my invention, what I claim is: j

1. A pair of electrical conductors for'use in a' circuit, each.conductor consisting of. two wires connected. n m l p a heir ends,

the plane of one pair of wires being perpendicular to the plane of theother pair.

2. A pair of electrical conductors each con- SiStiIl" of two wiresconnected to form a loop, 5 the pi a'ne of one loop being perpendicularto the plane of the other.

3. In an arrangement of the class described constituting two portions ofan electrical circuit, each portion consisting of a pair ofsubstantially straight wires con- 10 nected in multiple at their ends,the plane of one pair of wires being perpendicular to the plane of theother pair.
